Next part.
How we did it:
Now your door may be opened and you can replace the broken latch!
We hope this can help someone else in the future.
How we did it:
- Make space. Remove the back seat and passenger seat and remove interior of the B-pillar.
- Measure where to make the drill hole. We assumed that the driver door is a mirror of the passenger door and measured on the driver door and reflected it on the passenger side and put a marking where to drill.
Well, this was not easy because almost everything in the car is curved and have depths so it was hard to find a reference point. We used measuring tape, spirit level and plumb line.
- Make the drill through the B-pillar and plastic of the latch! We started with a small drill and moved up to 18 mm and drilled about 45 mm deep. But be careful not to drill in the latch more than the plastic, do not brake the mechanics you want to pull and push.
- If you were lucky as us you hit the spot with one drill. Now you need to pull and push the arm (6). We made a "fishing hook" and used a screw driver.
Now your door may be opened and you can replace the broken latch!

We hope this can help someone else in the future.
